If I open the devshell for the kernel (bitbake -c devshell linux-yocto-custom) I can see in the git log that the first patch set was applied.  The second patch set exists but is not applied.  If I call "guilt push" repeatedly from the devshell, the patches from the second set are cleanly applied.  My guess is that something doesn't like the second SRC_URI_append call.  Any ideas on how to fix it?

It shouldn't matter. Let me try and set up something that reproduces the
problem and get back to you.

Strangely .. I'm actively debugging something similar here already, so I
may be able to re-use it.

Stay tuned.

Out of curiosity, have you tried this on master ?

Cheers,
